And a flange 66c is fixed at an intermediate position of the screw rod 64, and a spring 66d for pressing the screw rod 64 in the distal direction is attached to the screw rod 64 so that the spring 66d is elastically attached to the flange 66c. A shaft 66a is provided, and a cam plate 66b fixed to a handle 66 is fixed to the shaft 66a. When the handle 66 is moved upward, the flange 66 is formed by the cam plate 66b.
By pressing c, the screw rod 64 is largely moved to the base side to open the gap between the hulling rolls 33 and 34. It is to be noted that providing a radius at the corner of the cam plate 66b facilitates the operation.

[0016]

Next, the operation will be described. When rice is put into the supply hopper 30 and the switching valve 62 of the supply hopper 30 is switched to one side so that the rice is supplied to the hulling rolls 33 and 34, the rice is hulled and the rice rag is sucked by the air selection path 35 and the machine The hulled rice is discharged to the outside, falls into the mixed rice receiving trough 38, is sent back by the conveyor 39, is fried by the mixed rice bucket elevator 5, and is stored in the fixed storage tank 6. Second trough 4
The No. 2 product that has fallen to No. 1 is fried in the No. 2 slower 43 and returned to the return paddy trough 44, and returned to the return room 6 in the Back thrower 54.
Returned to 1.

When the opening / closing shutter of the fixed storage tank 6 is appropriately opened while viewing the inside from the inspection window 60,
The liquid is supplied from the fixed storage tank 6 to the distribution device 8, moves to the division port 20 by the vibration of the bottom plate 19 of the distribution device 8,
And supplied to the sorting plate 9 of each stage. The sorting plate 9 swings horizontally horizontally by a cam wheel 12 rotated by a motor 13. Since a large number of swinging projections which can swing to the right in the drawing are formed on the plate surface of the sorting plate 9, specific gravity is high. Heavy brown rice moves to the right side in the figure, light paddy rice moves to the left side by reaction, and unmixed mixed rice is distributed in the center. The brown rice gathered in the brown rice discharging section 23 on the right side falls into the brown rice outlet 48 and is transported by the one-axis opposite spiral 51 so that the impeller 5
It is jumped up by 3 and taken out by the finished rice thrower 4. In this case, the upper end discharge portion 55 of the finished rice slower 4 is formed in the bent flow path 56 as shown in FIG. 7, and when the grain accumulates in the bent flow path 56, the wind of the impeller 53 is not discharged and returns from the return air path 57. Dust does not scatter because it is returned.

In the above description, the present application is based on the assumption that one of the hulling rolls 33 is fixed at an intermediate position of a support arm 67 by a shaft 33a, and the lower end of the support arm 67 is fixed to a frame by a shaft 34b. A top 65 having a screw hole at the upper part of 67 is fixed with a shaft 34c, a screw is engraved at the tip, and a tip of a screw rod 64 having a rotating handle 63 at the base is screwed into the top 65 and protrudes from the top 65. The screwed portion is inserted into a bearing 66e fixed to a frame so as to be able to freely enter and exit, a flange 66c is fixed at an intermediate position of the screw rod 64, and a spring 66d for pressing the screw rod 64 in the distal direction is attached to the screw rod 64, and The cam 66b fixed to the handle 66 is fixed to the shaft 66a, so that when the rotary handle 63 is rotated, the hulling roll interval is reduced. Can be fine-tuned When moved downward the handle 66,
The flange 66c is pressed by a cam plate 66b to
4 is largely moved to the base side, and the hulling rolls 33, 34
The interval between them can be widened to respond to the introduction of foreign matter.

The sorting state of the sorting plate 9 can be seen through the see-through window 17, but if the grain is too close to the brown rice discharge section 23, the right and left inclination is not enough, so that the switch is not used. 3, the first adjusting motor 14 shown in FIG. 3 is energized, and the screw rod 15 is rotated to raise the right side of the selection plate 9;
Is reversed to lower the right side of the sorting plate 9. Further, when a little rice is mixed in the brown rice extracted by the finished rice thrower 4, since the position of the first partition plate 21 is too close to the left, the second adjustment motor 26 is energized. Then, the first partition plate 21 is moved to the right by rotating the screw rod 27.

In the above sorting, the mixed rice dropped from the mixed rice outlet 49 is moved to the left by the one-axis counter spiral 52, collected in the mixed rice receiving trough 38, and is fried by the mixed rice bucket elevator 5. Further, the paddy rice taken out from the paddy rice outlet 50 is collected in the return paddy trough 44, returned to the supply hopper 30 by the return thrower 54, and crushed again.

In the above description, when the rice hulls are included in the dust discharged from the rice hull discharge blower 3, since the wind of the impeller 36 is too strong, the suction port is adjusted to be small.

[0022]

According to the present invention, when the hulling rolls 33 and 34 are juxtaposed below the supply port 32 of the hulling unit 1, the shaft 33a of one of the hulling rolls 33 is positioned at an intermediate position of the support arm 67. The support arm 67 is fixed at the lower end of the support arm 67 to the frame by the shaft 34b, and the top 65 has a screw hole at the upper part of the support arm 67.
With a shaft 34c, a screw is engraved at the tip, and the tip of a screw 64 having a rotating handle 63 at the base is screwed to the top 65, and a flange 66c is fixed at an intermediate position of the screw 64,
A spring 66 for pushing the screw rod 64 in the distal direction is provided on the screw rod 64.
d, a shaft 66a is provided near the flange 66c, and a cam plate 66b fixed to a handle 66 is fixed to the shaft 66a.
6b presses the collar 66c to move the screw rod 64 largely toward the base side. Thus, when the rotary handle 63 is rotated, the hulling roll interval can be finely adjusted and the handle 66 can be finely adjusted. When the is moved downward, the flange 66c is pressed by the cam plate 66b to move the screw rod 64 largely toward the base side, thereby increasing the interval between the hulling rolls 33 and 34, thereby making it possible to cope with the introduction of foreign matter.
